Fixed: ColourOutlines algorithm now spreads non-masked pixels in four directions rather eight. This prevents introducing non-border colors into the texture's non-masked/masked edge, which can result in visible artefacts if subsequently put through the hq2x algorithm (it doesn't care that the pixel is masked out when interpolating color).
